Task Information: GOO students are to maintain a glossary of terms associated with students’ mathematics learning. Terms included may be mathematical terms or may be terms associated with students’ mathematical development, such as subitising. For each term in the glossary a brief explanation should be provided, together with an example. Where appropriate a visual representation should be included (can be copied from a website, or created in word and added as a image [go to insert shapes/new drawing canvas and use the tools like the freeform line to create the image], or hand drawn and photographed and added as a image). Assessment criteria
Comprehensiveness of glossary

Area
The size inside a flat shape. Measured in 'squares'. E.g. all these shapes have the same area of 92. Measure the area of a rectangle: width x height.
Rounding means reducing the digits in a number while trying to keep it's value similar.
The result is less accurate, but easier to use.
This is the common method
Decide which is the last digit to keep
Increase it by 1 if the next digit is 5 or more (this is called rounding up)
Leave it the same if the next digit is less than 5 (this is called rounding down)
... bringing two or more numbers (or things) together to make a new total.Here 1 ball is added
to 1 ball
to make 2 balls: Using Numbers it is: 1 + 1 = 2
And in words it is
"One plus one equals two" http://www.mathsisfun.com/numbers/subtraction.html
"Waiter, I would like a 7 and a 3, please..." NO, not THAT type of ordering. I mean putting them in order ...To put numbers in order, place them from lowest (first) to highest (last). This is called "Ascending Order" (think of ascending a mountain)
Example: Place 17, 5, 9 and 8 in ascending order.
counting- we use numbers to count backwards and forwards, we count things to count how many things are there
Any number you can use for counting things: 1, 2, 3, 4, 5, ... (and so on).Does not include zero.Does not include negative numbers.Does not include fractions (such as 1/2 or 3/7)Does not include decimals (such as 0.95 or 1.3)

Example: In 352, the place value of the 5 is "tens"
Example: In 17.591, the place value of the 9 is "hundredths"

- Leave it the same if the next digit is less than 5 (this is called rounding down)
Example: 243 rounded to the nearest ten is 240 (because 3 is less than 5)http://www.mathsisfun.com/definitions/rounding.html

"One plus one equals two"

and you subtract 2,
you will be left with 3
This would be written:
5 - 2 = 3http://www.mathsisfun.com/numbers/subtraction.html
